With the development of modern information technologies, relying on nanotechnologies and remote sensing, a number of systems can be envisaged that allow for monitoring of the negative externalities generated by producers, consumers or travelers - road pricing schemes or individual emission...

This article was written for a collective book published by Delga Publ., gathering together contributions on contemporary China, in particular those presented during a conference organized at the French National Assembly in March 2013. It proposes critical comments on La Voie chinoise written by...

This paper presents a theoretical model of remanufacturing where a duopoly of original manufacturers produces a component of a final good. The specific component that needs to be replaced during the lifetime of the final good creates a secondary market where independent remanufacturers enter the...

Since the 1980s, developing countries started adopting telecom reforms due to pressures from international institutions. However, Middle East and North African (MENA) countries lagged in adopting such reforms. Even after introducing telecom reforms in the MENA region beginning in 1995, not all...

Using a database of more than 1,100 firms in the MENA region, this article looks at the determinants of demand for trade credit, particularly access to bank credit, size, age and the quality of the firm's financial structure. We show that the difficulty of gaining acces to bank credit positively...

The overlapping expectations and the collective absence of arbitrage conditions introduced in the economic literature to insure existence of Pareto optima and equilibria when short-selling is allowed and investors hold a single belief about future returns, is reconsidered. Investors use measures...

In a stochastic financial exchange economy, two financial structures are equivalent if, for each given state price, regardless the associated arbitrage free price, the marketable payoffs are identical. The key property of two equivalent financial structures is that, when associated with any...

This article reconsiders the theory of existence of efficient allocations and equilibria when consumption sets are unbounded below under the assumption that agents have incomplete preferences. It is motivated by an example in the theory of assets with short-selling where there is risk and...

Two financial structures are equivalent if, for each given state price, the images of their full payoff matrices of these financial structures are equal. The main consequence of this definition is that, regardless of the standard exchange economy ?, the existence of a financial equilibrium in an...

We consider a stochastic financial exchange economy with a finite date-event tree representing time and uncertainty and a financial structure with possibly long-term assets. We exhibit a sufficient condition under which the set of marketable payoffs depends continuously on the arbitrage free...
